Improvement in combined cultivator and seeder



Nrrn 'rares a'rnsi Speciiication forming part of Letters Patent No. 96,27H, dated October 26, 1869; antedated October 16, 1869.

To @ZZ whom, it may concern:

Be it known that I, SrLAs C. SoHoFIELD, of Chicago, in the, county of Cook and State of Illinois, have invented a new and useful Iniprovement in a Combined Cultivator and Seeder, and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings and the letters and figures marked thereon, which form a part of this specication, in which- Figure l represents a top or plan view of my improved machine; Fig. 2, a side elevation ofthe same; Fig. 3, a rear elevation thereof; Fig. 4, a transverse section ofthe seed-box; Fig. 5, a longitudinal section of a portion of the seed-box; Fig. 6, a front elevation of one of the plow-standards with plow attached; Fig. 7, a side elevation of the same, and Fig. 8 a sectional View at the line rv in Fig. 7.

My invention is an improvement on my combined cultivator and seedingmachine patented July 17, A. D. 1866; and it consists in pivoting the angle-beams of the cultivator to lo the main beams, so that they can be adjusted to an angle thereto; in the metallic elbow for adjusting the same; in the swivel-plate with which the plow-standard is connected with the beam; in the metallicl stall provided with a claw for holding the chain to regulate the depth of the plows in the soil; in the combination of the said metallic stall with the treadle and chain, in the method of securing the bolts or rivets to the plow, hereinafter fully described; and in the construction of the paddles which agitatethe grain in the seed-hopper, and the method of fastening the same to the rock-shaft.

To enable those skilled in the art to understand how to manufacture and use my improvements, I will proceed to describe the saine with particularity.

rlhe same letters of reference refer to the corresponding parts in the different gures.

The main frame A of my machine is supported on two standards, B, which project upward from the short axles C of the wheels.

The seat-beam D is rmly secured to the frame A of the machine, and extends back, so that the weight of the operator will balance said frame and seed-box D, which is attached to the front of the frame, or to the uprights E, which are attached to the frame.

The main plow-beams F are attached to the uprights E by a hinge-joint, as shown in Fig. 2, and to these beams are attached the anglebeams H in such a manner that they can be adjusted so as to form different angles with the main beam or the line of draft, and thereby regulate the width of the cultivator and the distance between the furrows of the plows.

, The said angle-beams are held at any desired angle by means of the elbow-plates I, the ends of said plates being attached to the angle-beam, and there being holes in one end of the plate for adjusting the angle of the two beams. The plow-standards are connected with the beams by means of the swivel-plate J. By making a single plate it can be made with the ribs on the side, between which the bolt-head ts to keep the bolt that passes through the top of the plow-standard from turning, and also by tightening the nut on said bolt the standard is clasped and secured at any angle of inclination desired; also, by loosening the nut on top of the plow-beam the standard and plows can be turned at any angle to throw soil to or from the corn.Y

K K are braces bracing the plow-standards, and they are so made that they can be adj usted to give the plow-beam the required slant. The plows are made with top and bottom alike,

so that they can be reversed when one point becomes worn, and they are secured tol the standard by means of the bolts L, which are made with a shoulder, S, to rest against the back of the plow-plate, and are headed down on the front of the said plate, so as to form a smooth surface, and at the same time be firmly and solidly secured to the plow-plate, as clearly shown in Figs. 7 and 8. I place a block, M, beneath the plow-plate, one side of said block being concave, so that it iits to a round standard, which enables me to turn the plow sidewise on the standard at any angle by simply loosening the nut and strap N, which secures the plow and bolts to the standards. I attach standards O to the top of the frame A, to which metallic stalls I are secured by bolts and nuts; and there are also standards Q attached to the plow-beams F, which extend up through said stalls, as shown. 'Ihere are also chains R attached to treadle-levers T, and by hitching said chain on the claws U of the stall P the cultivator may be suspended at any desired height, and when it is so suspended the trice.

b bator can throw the plows from the ground i y s] :nply pushing down the foot end of the Ale-levers T with his feet, the standards Q slipping through the stalls P. V V are braces extending from the outer ends ofthe axles to the main frame, and WV are braces bracing the plow-standard that is attached to the crosspiece Y.

Z is a vibrating arm, which extends into the seed-hopper and rocks the rock-shaft, being operated as descrbrd in my patent above referred to.

The paddles b are made in two parts, which clasp the rock-shaft at the top, as shown in Fig. 4. The two parts are held together by the bolt c, and can be loosened and adjusted on the rock-shaft by simply loosening the nut on the said bolt c. The use of the paddles is to agitate the grain in the hopper and cause it to fall `uniformly through the bottom of the said hopper. There is a slide, d, in the bottom of the grain-hopper, which is operated by the lever e, to open and close the openings in the bottom of the hopper, to regulate the escape of grain therefrom.

The top of the seed-hopper is made in two parts, which are connected together with the parallel hinges, and so that while one part is firmly secured to the top of the hopper the other part will swing out, as shown by the dotted lines h in Fig. 1, to open the hopper for the admission of grain.

Having thus fully described the construction and operation of my improved machine, what I claim, and desire to secure by Letters Patent, is-

l. The combination ofthe main beams F and angle-beams H, when constructed and operated substantially as and for the purposes specified.

2. The elbow-plates I. when constructed substantially as described, and used for the purpose of adjusting the angle of the bea-ms F and H, substantially as specified.

3. The swivel-plate J. when constructed and operating substantially as and for the purposes described.

4. The metallic stall P,when constructed and operatin g substantially as and for the purposes specified.

5. The combination of the treadle T, chain R, and metallic stall l?, when arranged and operating substantially as set forth. u
